Help transposing to another key

I'm transposing something written in the key of A to the key of G as I'm finding it easier to sing this way

In the A key there is a call for F#m chord so I'm thinking it should go to an E#m chord and I don't think there is any such chord. If there is, how would I finger it and if there isn't, could someone make a suggestion as to what might fit.
